"HTML5" mode determination is based on the HTML 5 draft of 2008-01-22 plus this correction.

"IE7" mode determination is based on this description.

The source data is 131,072 randomly-selected HTTP URIs from the Open Directory Project, downloaded on 2008-02-26.

The 'doctype' of a page was approximated as the first string matching the regular expression (?i)<!doctype[^>]*?>. (This under-estimates the number of quirks-mode pages, since it ignores any content preceding the doctype). All whitespace was then collapsed into single space characters, and the strings lowercased.
